aoData.push({ "name": "CompanyID", "value": MasterRecordID });

$.getJSON(sSource, aoData, function (json) {
fnCallback(json)
if (json != null) {
document.getElementById("hdTot").value = json.iTotalDisplayRecords;
if (json.iTotalDisplayRecords == 0) {
alert('No Record Found');
}
else {
//$("#spGetAll").css('display', 'block')
}
}
else {
alert('Som problem occured');
}

}
);
}

"fnInitComplete": function () {

if (document.getElementById("hdTot").value == "0") {
return;
}
else {

new FixedColumns(oTable, {

"iLeftColumns": 3,
